That's pretty much it. The decomposition process seems to make the separation harder...

[Arkcon]

I think we're going to need a little bit more context to give you a useful answer.  I don't even know where to begin to ask you more ... what scale?  What else is there?  Why do you want to do this?  Do you need the sucrose back?  What does your lab look like?  I moved your post to High School, but even I can't guess what resources you have at your disposal.

[ch3mistrydude]

I don't need the sucrose back.

[billnotgatez]

I would like to know the simplest way to separate sucrose from an aqueous solution.

Just to make sure of the question.
You have only water and sucrose?

[ch3mistrydude]

Also ammonia and ethanol and other compounds. Do other compounds get stuck in the sucrose if you evaporate it to burnt sucrose? My aim is to salvage the other stuff than sucrose.

@ch3mistrydude
Just to make sure we understand your needs.
So you have water with a bunch of compounds dissolved in it to include sucrose.
You want to remove the sucrose only and leave a aqueous solution of the rest of the compounds?
Do you know all of the other compounds possibly in this mixture?

[ch3mistrydude]

There's too many other compounds in the mixture to mention. Please tell me what info you need to determine the best course of action, and i will tell you the neecessary info.

I was originally going to say you might look at distillation and here is a WIKI article to assist you.
http://en.wikipedia.org/wiki/Distillation
In this case rather than removing the sucrose, you leave it behind and recover everything else as output. But, we do not know if all of the compounds in your solution would transfer.

Someone else might give you a chemical reaction like the ones suggested on the sucrose WIKI page
http://en.wikipedia.org/wiki/Sucrose#Thermal_and_oxidative_degradation
but that might leave a compound behind you do not want in your results.

And of course if you wait, someone here might have another idea, but you seem to have a moving target as to your question.

[Borek]

There are too many unknowns here, trying to guess what you want and what you have is a waste of time. If you have a well defined question we can help you, if you want us to play a guessing game - it won't work.

[ch3mistrydude]

I basically just want to know, that does distillation work, even if my target compounds boilung point is much higher than the sucroses decomposition point.

[Borek]

There is no such thing as "sucrose decomposition POINT". Decomposition is a continuous process that doesn't occur at a constant temperature like boiling or melting.

@ch3mistrydude
From the WIKI
Sucrose
https://en.wikipedia.org/wiki/Sucrose
Melting point None; decomposes at 186 °C (367 °F; 459 K)
Solubility in water 2000 g/L (25 °C)

Maybe you do an experiment.
Put a teaspoon of sucrose in a cup of water and place it in a 400 F oven for 1 hour and look at the results
Repeat using a teaspoon of sucrose and a teaspoon of sodium Chloride and look at the results.
Report the results back here.

[Zyklonb]

Heat the solution to 200 deg. C in an autoclave, filter the carbon.

[ch3mistrydude]

The spoblem just is that it gets all to be just clumps of carbon. I think the other stuff is stuck to the carbon...

[Borek]

I told you this guessing game is a waste of time. If you will not clearly explain what you have and what you want, you won't get any help.
